Parts for your 2015 Audi Q5-Centre bearing

2015 Audi Q5 centre-bearing: what it is, why it matters, and when to sort it out

According to Audi’s factory workshop information (erWin/ELSA, Q5 Type 8R, Drivetrain – Propeller Shaft) and the official Audi parts catalogue (ETKA, Model 8R, Group 52 – Propeller shaft), 2015 Audi Q5 quattro models use a two-piece propeller shaft with a centre support bearing. This bearing isn’t relevant on any front-wheel-drive variant (where offered in some markets), because there’s no rear prop shaft to support.

On a 2015 Q5 quattro, the centre-bearing sits midway along the prop shaft, cradled in a rubber isolator and bracket. Its job is to support the two-piece shaft, keep the driveline aligned under load, and soak up vibration so the cabin stays smooth. It also helps the universal/CV joints do their thing without chatter, which protects the transfer case and rear diff over the long haul.

It’s not a scheduled “service item”, but it’s smart to eyeball it during routine servicing. Tell-tales that the centre-bearing or its rubber support is getting tired include a thump on take-off, a rumble or buzz between about 60–100 km/h, or a droning vibration under load that eases off on overrun. Visually, look for a torn or sagging rubber carrier, shiny witness marks where the shaft has been rubbing a heat shield, or loosened bracket fasteners. Rule out wheel/tyre, engine mount and rear diff bush issues while you’re there.

Replacement approaches vary. Audi typically supplies the prop shaft as a complete, balanced assembly, and that’s the factory-preferred fix. Aftermarket centre support kits exist, but they demand careful pressing, alignment and balance control. Whichever route is chosen, mark the shaft and flanges before removal, keep the halves in phase, and tighten with the vehicle at normal ride height. Use new fasteners where specified and follow torque specs and any preload instructions in ELSA to avoid introducing a vibration. A quick road test over a range of speeds and light/heavy throttle will confirm it’s all happy.

Australian and New Zealand conditions—long distances, corrugated roads, towing and beach runs—can age the bearing faster. If the Q5 is carrying big kilometres or has spent time on rough tracks, a preventive inspection of the centre-bearing and prop shaft mounts is time well spent.

• Fitted on 2015 Q5 quattro: Yes, centre-bearing is used.
• Fitted on 2015 Q5 front-wheel-drive (if applicable): Not used, as there’s no rear prop shaft.

Popular questions

Does every 2015 Audi Q5 have a centre-bearing?
Most 2015 Q5s in Australia and New Zealand are quattro and do have a centre-bearing on the two-piece prop shaft. Any front-wheel-drive variant (where sold) won’t have one because it doesn’t run a rear driveshaft. A quick check of the VIN build data or a look underneath for a prop shaft to the rear diff will confirm it.

How long does a centre-bearing last and what are the warning signs?
There’s no fixed lifespan—many last well past 150,000 km—but harsh roads, towing and salt exposure can shorten it. Watch for a dull thump on take-off, a mid-speed vibration under load, or a humming/booming that changes with throttle. A sagging or split rubber carrier is the visual giveaway.

Can just the centre-bearing be replaced, or is a full prop shaft needed?
Genuine parts are typically supplied as a complete, balanced shaft. Some workshops fit quality aftermarket centre supports, but it requires precise pressing, phasing and alignment to avoid new vibrations. For peace of mind, many choose the full assembly, for budget repairs, a reputable support kit and careful installation can work well.
